| Abstract: |
| The application of antioxidant L60（its main component was derived from lignin） in natural
rubber （NR） was studied and compared with antioxidant 264，antioxidant 2246，antioxidant 445 and
antioxidant 4020. The results showed that，antioxidant L60 could reduce the curing speed of the compound.
The hot air aging resistance of the vulcanizate with antioxidant L60 was better，and the ozone aging resistance
was comparable to that of the vulcanizate with antioxidant 264. Moreover，antioxidant L60 had little effect on
the thermal decomposition temperature of NR vulcanizate |
